· What sort of cabling is suitable for Fast Ethernet protocols?
The most popular is the TCP/IP suite of protocols
Ethernet is a set of protocols to establish a LAN.
On a Mac, as on everything else, PPPoE is used to configure Point to Point Protocols over Ethernet which allows communication between computers connected on an Ethernet network.
It's a network operating using the Ethernet protocols at speeds of 1,000,000,000 bits per second or higher.
They can support multiple higher-layer protocols, and Ethernet 802.3 frames cannot.
because they can support multiple higher-layer protocols
Which parts of an Ethernet frame are Wireshark and other protocols analyzers unlikely to capture
a. because they can support multiple higher-layer protocols, and Ethernet_802.3 frames cannot
If the mainframe were using TCP/IP then you don't need to do anything except route the traffic to it. If the protocols are not Ethernet on both the mainframe and the LAN then you would need a gateway to convert the protocols back and forth from the mainframe.
Ethernet is the most popular networking technology used in LANs. Fast Ethernet is used to refer to any version of Ethernet that meets or surpasses the 100 Mbps transfer speed.
Arpa encapsulation must be used to enable Ethernet II frame type on your Ethernet.
